WARP-BEAM FOR Looms.

SPECIFICATION forming part of Letters Patent No. 729,496, dated May 26,1903 Application filed January 1'7, 1902- Serial No. 90,200. (No model)To all whom it may concern..-

Be it known that Lnmsrina J occur, a citizen of France, residing atSouth Manches! ter, in the county of Hartford and State of(.onnecticut,'have invented certain new and useful Improvements in-XVarp llcams for Looms, of which the following is a specification,reference being had therein to the aecompanying drawings.

My invention relates to new and useful improvements in warp-beams forlooms, and its object, among other things, is to providea beam ofcompact anddurable construction having means whereby the flangesemployed for regulating the width of the warp on the beam may besimultaneously adjusted from or toward each 01 her.

\Vith these and other objects in view, the

invention consists in the novel construction and combination of partshereinafter more fully describedand claimed, and illustrated in theaccompanying drawings,showing -the preferred form of -m y im z'entipn,and in .WhiGh- I I Figure 1 is a plan View of the beam. Fig. 2

Fig. 3 is a vertical longitudinal section thcrethrough. Fig. 4 is asection on line 4 4, Fig. 3, and Fig. 5 is an end view. v

Referring to the figures by numerals of reference, 1 is a cylindricalbeam formed of suitable material and having longitudinally-extendingslots 2m each end thereof. The ends of the beam are fitted into recesses3, (shown in dotted lines in Fig. 3,) formed in the inner faces ofheadsi; Each head is provided with an angular groove 5 and a hub U, thelatter being adapted to receive a suitable set-screw 7.

'- portions thereof lying Arevolub'le shaft Sis arranged longitudinallywithin the center of the beam 1, and those within the slots 2 arethreaded in'opposite directions, as shown at S). The ends of the shaftare squared, as at 10, and are adapted to be engaged by a cranlg' 11 orother suitable device, whercl' ysaid shaft may be readily tnrned. The st-screws 7 serve to lock the shafti'rat'terit has been revolvedsut'ficientlv Sliding blocks 1 areal-ranged withinthe slots2 and'aromounted on andengagc the threaded portions 5. o shaft 8. Secured to eachend of each block 12' isan cal-13, extend their ends by means of screwsable linear measure indicating the distances of the flangesv from thecenter of the beam. It will be noticed that the indicating-numer= alsupon the measure are so arranged that the distance may be read fromeither side of thebeam.

As shown in the drawings, the heads 4 are secured to the beam ends bymeans of screws or bolts 19. If desired, however, said heads and beammay be formed in'a single piece.

It is thought that the operation of the device will be readilyunderstood from the foregoing description. \Vhen it is desired toadvance the flanges 14, the set-screws 7 are loosened, the crank isplaced on one of the ends 10, and the shaft is turned so as to move theblocks 12 in either direction until the indicator 17 registers with thedesired graduation. As both circular flanges move in oppositedirect-ions simultaneously and at the same speed, it will be obviousthat the distance of both flanges from the center-will be shown by theone indicator. g

It will be seen that the device is extremely simple and compact and theparts may be accurately and quickly adjusted.

In the foregoing description I 'have shown the preferred form of myinvention, but I do not. ll mit myself thereto, as I am aware thatmodifications may be-made therein without departing from the spirit orsacrificing the advantages thereof, and I therefore reserve the right tomake such changes as fairly fall within the scope of my invention.

l laving thus fully described my invention. what I therefore claim asnew, and desire'to secure by Letters Patent, is.

In a warp-beam for looms, the combination with the cylindrical beamhaving longitudi- IOU nally-arranged slots in each face end thereof, andthe he ads on the beam each provided with a hub and a groove; of a shaftmounted longitudinally Within the center of the beam havingoppositely-arranged screw-threads mounted in the slots, and blocksslidably ad I justable in said slots having semicircular flanges thereonprovided with ears at right angles therewith so as to detachably securethe flanges to the blocks, agraduated measure extending longitudinallyacross the from 1 face of the beam, and the semicircular bands alsodetachably secured to the said ears and extending over the measure so asto coact with the graduations'thereon, substantially :5

as specified.

In testimony whereof I afiix my signature in presence of two witnesses.
